With Hitachi LUN Manager, open systems Logical Units LUNs can be defined, configured, and maintained. There is no more waiting for the hardware vendor to come and make configuration changes. Hitachi LUN Manager includes an easy-to-use, GUI-basedinterface that allows the easy definition of paths for LUNs, the reconfiguration of LUN-to-portassignments, or the viewing of the Lightning 9900 remote service information messages. Because the Hitachi LUN Manager can assign multiple paths to a single LUN, support of alternate path failover, path load balancing, and clustered systems is possible. Running on a standard Windows-basedPC connected to the storage subsystems by a dedicated LAN, Hitachi LUN Manager can support up to eight Lightning 9900 systems Hitachi CruiseControl Hitachi Data Systems Hitachi SANtinel Storage Maximizer Hitachi Data Systems Cost of Risk Analysis methodology CORA Professional Services and SupportProfessional Services Overview Data Protection Services Hitachi Data Systems Data Protection Services LabRemote Copy Assessment and Implementation Service Hitachi NanoCopy Implementation Service SAN services Professional Services and SupportContinuous Availability Service On-lineData Migration Service Hitachi Data Systems Software Portfolio Review and Analysis Service the Performance Experiment System Configurations for The 7700E used all 6GB drives Hitachi Data Systems ACP pair Glossary of Terms10BaseT 100BaseT Business Continuity Planning BCP Hitachi Data SystemsAvailability Back end CHIP GlossaryCARB Cache CORA Cost of Risk Analysis Hitachi Data SystemsConsistency Groups Control Frame Data Migration Disaster RecoveryGlossary Data Duplication ESA/390 Hitachi Data SystemsEBCDIC Electronic vaulting Fast write GlossaryFailover Fast Ethernet Front End File BackupHitachi Data Systems FICON Hitachi CruiseControl Hitachi FlashAccessGlossary HDmS Hitachi LUN Manager Hitachi Multiplatform Backup/RestoreHitachi Data Systems Hitachi InstantSplit Hitachi SANtinel Hitachi Rapid RecoveryGlossary Hitachi Resource Manager Java Hitachi Data SystemsHXRC Hitachi Extended Remote Copy HYPERtape Logical Unit Logical VolumeGlossary Lightning 9900 Series Meta-data Hitachi Data SystemsMBCP MIPS NanoCopy GlossaryMTBF MTTR Operating System Hitachi Data SystemsOn-linesystem Open system RAID Controllers Recovery TimeGlossary RAID Snapshot SwitchHitachi Data Systems SCSI Synchronous Virtual Logical Volume Image ManagerVolume Glossary Warm site Hitachi Data SystemsWorkload Australia/New Zealand Headquarters Hitachi Data Systems Worldwide OfficesCorporate Headquarters Asia Headquarters
